INDIVIDUAL APARTMENT IMPROVEMENTS
OVERVIEW
This Operational Bulletin is being issued to reflect changes in the rent laws regarding Individual Apartment
Improvements (IAIs).
This Operational Bulletin provides guidance to owners and tenants of apartments subject to rent control and
rent stabilization both inside and outside of New York City on how DHCR will review the installation of IAIs
when a complaint of rent overcharge has been filed or there is an investigation with respect to IAI installations.
An owner may be eligible for a rent increase for an IAI when there has been a substantial increase of dwelling
space, an increase in the services provided by the owner, improvements installed in the housing accommodation,
or new furniture or furnishings provided by the owner.
I. Notification Forms that Need to be Filed Irrespective of any Overcharge Complaint and/or
Investigation
Owners of apartments subject to rent stabilization or rent control must file electronically DHCR Form
RN–19N INDIVIDUAL APARTMENT IMPROVEMENT: NOTIFICATION, for IAIs made in vacant and
occupied apartments. In addition to the Notification Form, where tenant’s consent is required, owners must
file electronically DHCR Form RN–19C INDIVIDUAL APARTMENT IMPROVEMENT: TENANT’S
INFORMED CONSENT for IAIs made to occupied apartments. If there was a tenant in occupancy of the
apartment when the improvements were installed, then no otherwise permissible rent increase due to such
improvements will be recoverable without the tenant’s written informed consent to the rent increase.
